Titanium Dioxide

Optimization Potential

Existing Acrylic filters used in spray dryer were experienced short life times of only 6–12 months and high pressure drops. Failures were producing high emissions and required unscheduled system downtime, inspection, and change outs. High pressure drop led to deration of system and lower productivity.

Solution

Acrylic filters were replaced with GORE™ Acid-Resistant Aramid Felt membrane filters. System was optimized to prevent temperature excursions and a new blower was installed. Cleaning frequency was increased to maintain dP.

Results

Bag life was increase to 3,5 years and pressure drop was stabilized at 1.000 Pa throughout life of filters. Emissions and deration problem were eliminated and new bags and blower allowed increased production.
